Calculation of flat reinforced concrete slabs strengthened by post-stressed rebars in two directions.

Abstract

The purpose of the dissertation research is to carry out theoretical calculations and the experimental confirmation of the possibility of strengthening the flat reinforced concrete slabs with external stressed reinforcement, and influence of such strengthening on the subsequent operation of the slab under the increased load. The results of theoretical researches of the calculation of flat reinforced concrete slabs strengthening by external stressed reinforcement in linear and nonlinear formulation of problems are presented, and the results of two calculation variants are compared.
